Fig. 3 is the perpendicular structural representation that cuts open of the present utility model.
The specific embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.
As shown in Figure 3, of the present utility model pair of dynamic compressor comprises upper cavity die 20 and lower cavity die 21 with inaccessible formula extrusion molding knuckle mould, for being used to form the die cavity of knuckle exterior contour, simultaneously, be connected with the structure that guide pin bushing 16 cooperates by guide pillar 15 between the upper and lower die between the upper and lower die; The top, horizontal of upper cavity die 20 is provided with upper cavity die pressing plate 7, the top of upper cavity die pressing plate 7 up is disposed with punch pad 6, punch 5 and cope match-plate pattern 2, be connected by vertically disposed Tiebar structure between punch pad 6, punch 5 and the cope match-plate pattern 2, the middle part of upper cavity die 20, upper cavity die pressing plate 7, punch pad 6 offers and is used for the jet-bedding I that punch 5 moves downward, the lower end of punch 5 and jet-bedding I are equipped with and with the form of upper punch blank are carried out Closed Extrusion, form the last endoporus of knuckle; The bottom surface of lower cavity die 21 has been horizontally disposed with lower bolster 24 and lower bolster 27 downwards successively, the bottom of lower bolster 27 is provided with the low punch structure of being made up of push rod 22 and push rod 23, the middle part of lower cavity die 21, lower bolster 24 and lower bolster 27 offers the jet-bedding II of perforation, low punch structure and jet-bedding II are equipped with and with the form of low punch blank are carried out Closed Extrusion, form the following endoporus of knuckle.
As further improvement, between punch 5 and cope match-plate pattern 2, be provided with convex mould pad 4, be arranged with the punch spacing collar at the cylindrical of convex mould pad 4, simultaneously, between lower cavity die 21 and lower bolster 27, be provided with die backing plate 24, jet-bedding II is by die backing plate 24.In mould, the area of convex mould pad 4 and convex mould pad 24 is big and certain thickness is arranged, and its role is to prevent that drift and die from directly affacting upper and lower template with power or the lathe table top causes distortion, extrudes pit.Add after such backing plate, the unit are active force of punch-die can be dropped to below the 400MPa.
As further improvement, lower cavity die 21 is arranged with lower cavity die centre circle 25 and lower cavity die outer ring 26 successively along its cylindrical, upper cavity die 20 is arranged with upper cavity die centre circle 19 and upper cavity die outer ring 17 successively along its cylindrical, in this way upper and lower die is carried out stationary positioned, avoids inconsistent phenomenon to take place.
As further improvement, the knuckle mould also comprises baroclinic block 9, as with the fit structure of baroclinic block, the cylindrical of upper cavity die pressing plate 7 is provided with the face of baroclining, and baroclinic block 9 is provided with and the face of exerting pressure that baroclines the suitable shape of face, matches with the face of baroclining by the face of exerting pressure, upper and lower die is imposed thrust, top at baroclinic block also is provided with the baroclinic block fixed head, avoids baroclinic block to shake, and influence compresses effect.
In the present embodiment, between upper cavity die outer ring 17 and upper cavity die pressing plate 7, fix by screw 14 and alignment pin 8, fixing by screw 18 between lower bolster 27 and lower cavity die outer ring 21.
In this mold, because the diameter of blank is identical with the lower cavity die internal diameter, naturally locate by die cavity so can directly be placed on blank in the lower cavity die 21, then baroclinic block 9 is under the effect of double action hydraulic press outer slide, tightly push down upper cavity die pressing plate 7, thereby push down the die cavity that upper and lower die forms sealing.In stroke, guide pillar 15 slips into and realizes the location in the guide pin bushing 16; After ram travel finished outside, inner slide drove punch 5 and continues descendingly, and punch 5 carries out Closed Extrusion with the form of upper punch to blank, and push rod 23 is with the form of low punch another endoporus that is shaped simultaneously, thereby finished the forming process of knuckle.After shaping finished, baroclinic block was unclamped in the backhaul of outer slide elder generation, and the while pull bar is fixed on the outer slide up, and it is up to drive upper cavity die 20, and guide pillars and bushes separates, and die cavity is opened, and last push rod 22 promotes push rod 23 and ejects workpiece, finishes a forming period.
In this mold, last lower cavity die and punch, push rod adopts 4Cr5MoSiV1(H13) hot die steel.This type of material is widely used, and has than higher calorific intensity and hardness and has good toughness, thermal fatigue property and certain wearability under mesophilic condition, is suitable as very much the material of the easy loss mould of inaccessible this molding mode of extruding.Simultaneously, its heat treatment deformation is little, and the oxide skin performance tendentiousness that produces during air quenching is little, and the erosion effect that can resist metal, satisfies the forging free from corrosion requirement in surface.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present utility model.
